This is the real deal!

I've struggled for years maintaining chlorine and controlling algae in our above ground pool. We've only had our pool up and running slab out 3 weeks, but zero issues! This seems to dissolve quicker than other shocks I've used, which is a big plus. I use 1 packet of shock once weekly and by doing so my floating chloronator is able to maintain the correct concentration of chlorine for the week, even with daily pool use. I'll continue to purchase, even though a little higher priced because the product works! It saves me time %26 in the long run, money by not having to buy additional chemicals or worse, drain and refill the 10,000 gallon pool.
